how to get the "comment_count" in the meta ?

[liudatutu]

this is my code:

import youtube_dl
ydl_opts = {'forcetitle':'True','ignoreerrors':True,
'encoding':'utf-8','outtmpl':u'E:/Movie/%(title)s.%(ext)s'}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
meta = ydl.extract_info(
'https://www.youtube.com/watch?v=RGNTdUHN64Q', download=False)
print type(meta)
#print meta
print 'comment_count:',meta.get('comment_count','None')
